AvaLight-DHc Full-range Compact Light Source

Full-range Compact Light Source
Get the best out of two worlds with the
AvaLight-DHc. It has both a deuterium
light source and a halogen light source,
providing you with adequate light between
200 and 2500 nm for nearly all absorbance
chemistry applications. Deuterium emits
light between 200 and 550 nm, where
the halogen takes over up to 2500 nm.
Coupling this lightsource to the rest of
your spectroscopy system is easy with the
SMA connector.
Optionally the AvaLight-DHc is available in
a rack-mountable version, to be used in the
19” rack or the 9.5” desktop system.
• Combined Deuterium-Halogen
• Integrated TTL-shutter
A direct-attach cuvette holder CUV-DA (see
section accessories) is available for fluorescence or absorbance measurements.
This light source is recommended in settings with large fiber cables or directattachment to a cuvette holder such as the
CUV-DA, due to its relatively low output
energy. The integrated TTL-shutter makes
saving a dark measurement very simple in
combination with AvaSoft (extra IC-DB26-2
